The label on both fans clearly shows “T&T”, “7025H12B YD1”, “0.30A”, “12VDC”, and “QUALITY AND PERFORMANCE”. The 7025H12B model is also commercially documented as a 70×70×25 mm, 12 VDC, 0.30 A fan.
⚡ Function in the Electrical System
The assembly is intended for forced cooling of electronic and electrotechnical equipment. The two fans generate airflow through the system to promote dissipation of heat produced by inverters, power supplies, converters, electronic boards, electrical panels, and industrial equipment.
The two-fan configuration allows distributed cooling inside the equipment, while the common wiring facilitates connection to a single 12 VDC power supply.
🏭 Construction and Installation
The two fans are installed on a common support/wiring assembly, with pre-arranged electrical connection and a multipole circular connector visible in the photographs.
Each fan measures 70 × 70 × 25 mm, a particularly common size for compact electronic cooling systems. Commercial documentation for the 7025H12B model also confirms the 12 V / 0.30 A configuration and availability with wire connection.
The assembly can be installed directly into the equipment using the mounting holes present on the fan frames, checking beforehand the mounting spacing, airflow direction, and connector compatibility.
🌐 Applications
Suitable for:
-
photovoltaic inverters;
- power supplies and converters;
- electronic equipment;
- control panels and systems;
- industrial equipment;
- telecommunications systems;
- replacement of original ventilation assemblies.
🛡️ Safety and Product Condition
The product is used and working, with normal signs of use and the presence of dust/residue consistent with previous use. The two fans are complete, with wiring and connector present.
Before use, verify 12 VDC power supply, polarity, current consumption, fan rotation, and integrity of the wiring/connector.
⚠️ Do not connect directly to voltages higher than those specified. The assembly must be powered by a stabilized 12 VDC source compatible with the total consumption of approximately 0.60 A.
